Title: Collision-prevention controller for freight handling machine
Inventor: YOSHIDA SATORU
IPC: B66F9/24
Filed: 1987-06-19
Abstract: PURPOSE:To prevent collision of freight handling machines by dividing the movement of a freight handling machine and by checking on a possibility of collision for every divided movement. CONSTITUTION:A working command from a working command controller 11 is sent to positioners 8a, 8b via ground communication devices 12a, 12b and on board communication devices 9a, 9b of freight handling machines 1a, 1b. On the other hand, the current address of said freight handling machines 1a, 1b from position detectors 7a, 7b is sent to anticollision controller 13 via on board communicators 9a, 9b and ground communication devices 12a, 12b. Said anticollision controller 13 checks on a possibility of collision for freight handling machines 1a, 1b from the current address and working command and makes either of them have preference to the other for working, if there is such possibil ity of collision. In this manner, it is possible to prevent collision and to improve working efficiency.

Title: Gas insulated switchgear and transformer station using this device
Inventor: TSUKUSHI MASANORI
IPC: H02B7/08
Filed: 1995-06-20
Abstract: PURPOSE: To allow a transformer station to be constructed with a degree of freedom by locating a plurality of breakers that have an aspect ratio of a specified value or above on the same side about a main bus. CONSTITUTION: Main buses 5A, 5B are three-phase one-wire buses. Between the main buses 5A and 5B, vertical gas breakers (GCB) are arranged in line. At that time, the arrangement length is longer than the length they cross at right angles with the main buses 5A, 5B in a projected figure on a floor face. The GCB's are located in the order of the GCB for line 3, the GCB for linkage with the buses 9, and the GCB for transformer 6. Connections 10A, 10B between these GCB's are installed in parallel with the main buses 5A, 5B. When the GCB's 3, 9, 6 are three phase one-wire GCB's, the length per line of the GCB's 3, 9, 6 toward the main buses 5A, 5B is short and thereby the aspect ratio per line is 2 or more and smaller than a three-phase three-wire type. Therefore, a transformer station can be built up in a long and narrow belt-like structure.

Title: Fsk receiver
Inventor: MAEDA KAZUNARI
IPC: H04L27/14
Filed: 1992-06-15
Abstract: PURPOSE:To improve the accuracy of an oscillation frequency of a fundamental frequency oscillator inexpensively. CONSTITUTION:An output of an oscillation frequency of a fundamental frequency oscillator 6 multiplied by a multiplier section 7 and an output of an RF section 1 are mixed to convert the signal into an intermediate frequency signal and after the intermediate frequency signal is amplified, the result is demodulated. A voltage controlled oscillator is adopted for the fundamental frequency oscillator 6. The oscillation frequency from the fundamental frequency oscillator 6 is multiplied by a multiplier section 8 and the intermediate frequency signal is frequency-divided by a frequency divider section 9. When a carrier signal representing no data is received and there is no deviation in the oscillation frequency of the fundamental frequency oscillator 6, the conversion is implemented to make respective conversion frequencies coincident with each other. The frequency of each output from the multiplier section 8 and the frequency division section 9 are compared by a frequency comparator section 10. An output of the frequency comparator section 10 is converted into a voltage signal by a low pass filter 11. A control section 5 corrects a deviation in the oscillation frequency of the fundamental frequency oscillator 6 by an output cancelling an output based on data of the low pass filter 11 by using data after demodulation.
